PUMPING JAR.

Application led July 18, 1922. Serial No.. 575,893. I s

To all whom it may concer/L.'

lle it known that l, VINCENT `Dn PAUL SPLANE, a citizen or' the UnitedStates, residing at ljaintsville, in the county ot Johnson and State oflentucky, have invented certain new and useful Improvements in Pumping'J ars, of which t-he following is a specilication.

My said invention hasfor its purpose to provide a coupling and jarringconnection between the sliding or traveling' valve and the stationaryvalve ot' a pumpparticularly 'for oil wells, but adapted for any deepwell., and it consists chiefly in improvements in the details ofconstruction and arrai'igement of parts whereby many of thedisadvantages in the use and operation of such Vpump heretoforeexperienced are overcome and a very convenient and efficient device forthe purpose provided all as will be hereinafter more fully described andclaimed.

Referring to the accompanying drawings, which are made a part hereot`and on which similar reference characters indicate similar parts,

Figure 1 is a sectional'view through an oil pump at the point of thelocation ot the working barrel,' showing the valves and pumping jarconnection between them in elevation, and in the position they occupywhen the upper or slidin valve is in the position of the limit o itsup-stroke, and

Figure 2 a view on an enlarged scale showing the pumping jarsseparately, partly in section.

In said drawings the portion marked 10 presents the working barrel of apump, 11

and 12 sections of the pump casing, 13 the stationary valve, 14 thesliding or traveling valve, 15 the lower jar or rein, and 16 the upperjar or working rein of the connection.

The working barrel 10, the case vsections 11 and 12, and the valves 13and' 14 are in the main ot substantially a usual or any approvedconstruction and arrangement. Packing rings or cups 20, usually ofleather, are interposed between the lower edge of valve 14 and the upperedge of the socket 21 on the upper end of upper rein 16 and like cups 22are interposed between the lower edge of the stationary valve 13 and theup-per edge ot a cage or crown 23. Socket 21 takes thc place and servesthe purpose ot the crown or cage usually employed on the` lower end ofthe Sliding valve. By adjusting these crowns the packing is compressedmore orless to secure the desired tit of thel valves."

The pumping jars comprise ytwo interlocked links made ot steel, ormaterial that will stand any amountv of jarring service or strainwithout injury. The lower'jary 15 is formed with av screw-threaded bossor tang 17 on its lower end adapted to screw into' an internallyscrewthreaded collar on the upper end or' stationaryuvalve 13. The upperjar or working rein is Yformed with a tubular upper end on socket21finternally screw-threaded and adapted toY screw on to ascrew-threaded projecting boss' 24 on the lower end ot the sliding or.traveling valve 14. Said traveling valve 14 is attached to an operatingrod 18 which is connected to the pumping jack in the usual manner. 'Thelinks are formed with flat faces' atm25, 26, 27, 28 and 29 which contactat the limits of the movements of the links or jars. y, y

In assembling the parts for v operation the valves are properlyconnected by the pumping jarsl andgl as shown in Figure 1 and .hung tothe operating rod 18 and lowered into the pump. The lower valve be.

cause of its tapered lower end readily enters the top of working barrel10, the upper jar is loweredl until its lower end meets the lower insidesurface 'of the lower pumping jar and its upper surface meets the upperend of said lower jar making a do-uble contact, then by a series ofjarring strokes said valve-13 is driven to the lower end off the workingbarrel, its final` position being determinedl by measurement vor ashoulder 80, as will vbe readily understood. The pumpis then ready foroperation and operates in the usual manner, the stroke of the 'travelingvalve 18 beingvaried by the length of the links and theseare' made ofdifferent lengths to accommodate,l different conditions, the or# dinaryor usual; strokebeing approximately 18 inches.

These pumping jars are made to screw directly on to the standardtraveling and working valves or the type in common use, socket 21serving the purpose ot the usual crown to tighten the cups to thediameter of the working barrel. The whole is low ered into the well atone time, the lower or stationary valve being first seated, when thepump is ready for operation.

It will be understood of course that these pumping j arsv are designed`\forfatt'aclnnent to any valve rods or sucker rods and to be insertedin any size tube. The normal operation of the pump isnotdifferent .fromthat'.

commonly in use. Vhen, however, the

valve becomes mudded up or the working" .isreturned vto its seat in thelower end of said .working barrel, as heretofore, and the pumpingoperation. may continue. Thus thisidiiicultymay be .overcome veryquickly andthe necessityof pulling out the traveling valve-and thenlowering a. grapple and removing thestationary valve and thenreassembling the parts, one valve at a time as has beenl heretofore thecustom, is avoided.- Another advantage in the. use of jars of this.constructionis found when it becomes necessary to :pull the valves outof thewellas when thepacking cups are out or wor-nbysandr Bymyarrangement botlrthe. traveling. and stationary valvemay,b'el.removed.by one operation and the cups. adjusted or replacedA bynew ones, whereas .by theusnal .arrangement it is necessaryto pullthetraveling. valve and remove ,thefrods, then vrun the vrods back into thewellfwith `a grapple to pullout the standingvalve..v

Theseand ,otherl `obvious advantages result .from-the employment of mypumping jars, allas .will be readily understood.

Having thus fully described my said invention, what l claim asnew anddesire to secureloyV 'Letters Patent, .is

l. A pump comprising. a working. barrel, a stationary valve, a travelingvalve and interlocked pumping` jars connectingv said twovalves, onebeing connected to the upper end ofthe stationary valve and the othertoi .the flower 'endl of 4`the sliding. or working valve,saidfpumpingjarsbeing of uniform length-'whereby lwhen used for jarringpurposes a double Contact is made at the closing of the jars,substantially as set forth.

2'. A pump comprising a casing having a working barrel as a sectionthereof, a stationary valve'forservicel in the lower end of said workingbarrel, a traveling valve, and pumping jars connecting said valves, theupper ar being adapted to screw on to a screw-threaded boss or collar onthe lower end of the traveling valve and the lower jar being adapted toscrew into a screw-threaded collar on the upper endof a lower jar, saidjars being of uniform length, substantially as set forth.

3. A pump comprising a working barrel, a stationary valve, a travelingvalve, and interlocked link-like pumping 'jars connecting said twovalves, oneof saidpumping jars being connected withwthe upper'end of thestationary valve andthe other with the lower endof the sliding orworking valve, said valves being provided with packing and the uppervalve having said packing interposed between the lower. edge of thevalve casing. and vthe'upperedge of a socket formed 'inthe' upperend 'ofthe upper rein ofthe pumping jars, substantially as set forth'.

4. A pumpcomprising a working barrel, a stationaryl valve, a travelingvalve, and interlocked link-like pumping vjarsl connecting said valvesone of said. link-like jars being formed with a fiat faceA for receivinga blow from the othersaid jar, substantially as set forth.

5.y A` pumpcomprising a working barrel, a stationaryY valve, a travelingvalve, interlc-ked tpumpingjars.connecting said two valves, one to theupper. end of the stationary valve and rthe'vother to thelower end ofthe workingv valve," saidljars :being'of uniform lengthand'formed withkflat contactingvfaces adapted to meet at the extremes ofV the movementsof the sliding valve, substantially as set forth.

ln witness whereof, I have hereunto set my hand 'and 'seal atPaintsville, Kentucky this 19th dayof June, l;- D. nineteen'hundred andtwenty-two.-
